Why can't we use a HTTP request header to get rid of all cookie consent popups?
It would be hugely better to simply set some setting in your browser that would send a request header to every web site you visit that contains your GDPR preferences. Then every site would have to comply with this by default.
This could be a general purpose header that could send various user preferences, for example it could also tell the website the end user is a child under 13 years of age so the site wouldn't collect certain stats automatically to comply with US Coppa law.
To me this is an obvious solution that would be a lot easier to implement than all those GDPR popups and it would result in a much better usage. What do people think? Should HTTP standard be updated with such header? Or are there any disadvantages of this approach I'm not thinking about?
